Abstract

En stötfångarbalk består av en hattprofil (11) med ett lock (12). Locket är vänt utåt frånfordonet och har vertikala präglingar (21) vid stötfångarbalkens infästningspartier (18,19)och horisontella präglingar däremellan. Hattbalkens sidor (14,15) har präglingar riktade ifordonets längdriktning. A bumper beam consists of a hat profile (11) with a lid (12). The cover is facing outwards from the vehicle and has vertical embossments (21) at the mounting portions (18,19) of the bumper beam and horizontal embossments in between. The sides of the hat beam (14,15) have embossments directed in the longitudinal direction of the vehicle.

Description

537 086 fordonets längdriktning och förstyvar sidorna. Locket 12 har vertikala präglingar 21 vid infästningspartierna. I området mellan infästningspartierna har locket horisontella präglingar 22. Locket kan såsom visas ha ett hål 23 för en dragögla och det behöver inte täcka hattprofilen på utsidan om infästningspartierna. Centralflänsen 13 har motsvarande hål 24. 537 086 the longitudinal direction of the vehicle and stiffens the sides. The lid 12 has vertical embossments 21 at the fastening portions. In the area between the fastening portions, the lid has horizontal embossments 22. As shown, the lid can have a hole 23 for a pull loop and it does not have to cover the hat profile on the outside of the fastening portions. The central end 13 has corresponding holes 24.

Vid krockbelastning motverkar lockets vertikala präglingar 21 tendensen till att locket böjs inåt vid infästningspartierna och sidorna 14,15 viks mot varandra. Därigenom fördröjs den plastiska deformationen av infästningspartierna. lnfästningspartierna tar därför större last innan de börjar deformeras plastiskt.In the event of a collision load, the vertical embossments 21 of the lid counteract the tendency for the lid to bend inwards at the fastening portions and the sides 14,15 to be folded towards each other. This delays the plastic deformation of the fastening portions. The attachment portions therefore take a larger load before they begin to deform plastically.

Sidornas präglingar 20 förstyvar sidorna så att de tar högre last innan de börjar buckla.The side embossments 20 stiffen the sides so that they take a higher load before they start to dent.

Stötfångarbalken är bågformad sett uppifrån och de horisontella präglingarna motverkar lokal buckling när stötfångarbalken rätas ut vid krock. Lastnivån ökar brant och tvärsektionen behålls längre vilket medför att krockbelastningen överförs till infästningspartierna till dess dessa börjar deformeras och plastiskt ta upp krockenergin.The bumper beam is arcuate seen from above and the horizontal embossments counteract local buckling when the bumper beam is straightened in the event of a collision. The load level increases steeply and the cross section is retained longer, which means that the impact load is transferred to the fastening portions until they begin to deform and plastically absorb the impact energy.
